Designing for Interruptions and Backchannels: UX Patterns for Full-Duplex Voice Skills
GPT-Live can say 'mhmm', stay quiet while you think, and let you cut in mid-sentence. Turn that full-duplex behavior into concrete UX rules and a checklist for your own voice-agent skills.
Guardrails for Voice: Impersonation Limits, Safety, and Compliance in Voice Skills
OpenAI's GPT-Live ships predefined voices only, blocks cloning, and builds in teen safety. Translate those safeguards into a concrete publishing checklist for responsible voice skills.
The $10/$50 Question: Cost-Aware Routing Between Fable 5 and Opus 4.8
Fable 5 costs roughly 2x Opus 4.8. That doesn't mean run everything on the cheaper model. Here's a routing heuristic for deciding which turns deserve the premium tier.
